如何在Windows Phone 8中使用StoredContact.SetDisplayPictureAsync（IInputStream流）？

Question

请参阅下面的代码，如何将IsolatedStorageFileStream-obj传输到IInputStream-obj？谢谢！

using(IsolatedStorageFileStream stream = 
   IsolatedStorageFile.GetUserStoreForApplication().OpenFile(".."), FileMode.Open))
{
    await storedContact.SetDisplayPictureAsync(stream); // compile error
}

在WP8上：

using System.IO;

using(IsolatedStorageFileStream stream = IsolatedStorageFile.GetUserStoreForApplication().OpenFile("..", FileMode.Open))
    await storedContact.SetDisplayPictureAsync(stream.AsInputStream());
